((sqrt(x-1)-b-c))/a+((sqrt(x-1)-c-a))/b+((sqrt(x-1)-a-b))/c =3

Solución

\frac{( x - 1 - b - c )}{a} + \frac{( x - 1 - c - a )}{b} + \frac{( x - 1 - a - b )}{c} = 3

Solución

x = \frac{( 3 b c a + b ^{2} c + b c ^{2} + c ^{2} a + c a ^{2} + b a ^{2} + b ^{2} a ) ^{2}}{b ^{2} c ^{2} + 2 b c ^{2} a + 2 b ^{2} c a + 2 b c a ^{2} + b ^{2} a ^{2} + c ^{2} a ^{2}} + 1

Pasos de solución

\frac{( x - 1 - b - c )}{a} + \frac{( x - 1 - c - a )}{b} + \frac{( x - 1 - a - b )}{c} = 3

Encontrar el mínimo común múltiplo de

a, b, c : b c a

Multiplicar por el mínimo común múltiplo=

b c a

\frac{x - 1 - b - c}{a} b c a + \frac{x - 1 - c - a}{b} b c a + \frac{x - 1 - a - b}{c} b c a = 3 b c a

Simplificar

b c (x - 1 - b - c) + c a (x - 1 - c - a) + ba (x - 1 - a - b) = 3 b c a

Desarrollar

b c (x - 1 - b - c) + c a (x - 1 - c - a) + ba (x - 1 - a - b) : b c x - 1 - b^{2} c - b c^{2} + c a x - 1 - c^{2} a - c a^{2} + ba x - 1 - b a^{2} - b^{2} a

b c x - 1 - b^{2} c - b c^{2} + c a x - 1 - c^{2} a - c a^{2} + ba x - 1 - b a^{2} - b^{2} a = 3 b c a

Desplace

a la derecha

b c x - 1 + c a x - 1 + ba x - 1 = 3 b c a + b^{2} c + b c^{2} + c^{2} a + c a^{2} + b a^{2} + b^{2} a

Factorizar

b c x - 1 + c a x - 1 + ba x - 1 : x - 1 (b c + c a + ba)

x - 1 (b c + c a + ba) = 3 b c a + b^{2} c + b c^{2} + c^{2} a + c a^{2} + b a^{2} + b^{2} a

Dividir ambos lados entre

b c + c a + ba

x - 1 = \frac{3 b c a + b ^{2} c + b c ^{2} + c ^{2} a + c a ^{2} + b a ^{2} + b ^{2} a}{b c + c a + ba}

Elevar al cuadrado ambos lados:

x - 1 = \frac{( 3 b c a + b ^{2} c + b c ^{2} + c ^{2} a + c a ^{2} + b a ^{2} + b ^{2} a ) ^{2}}{b ^{2} c ^{2} + 2 b c ^{2} a + 2 b ^{2} c a + 2 b c a ^{2} + b ^{2} a ^{2} + c ^{2} a ^{2}}
